'CDLLAPSIIBLE DRINKING-CUP.

1'0 all whom it may concern.

Be it known that we, PA'rnIox A. BAY- LESS and HOWARD D. HENRY, citizens of the United fitate's, and residents of Oklahoma city, county of Oklahoma, Stateof Oklahoma, and El Reno, in the county ofCanadian and Sta-teof Oklahoma, respectively, have invented certain new and useful Improvements in Collapsible Drinkin Cups, of which the following is a specification, reference being had panying drawmg." 4

This invention relates to drinking cups, and the principal. object of the same is to provide a cup that can be folded into a small compass so ,that'the same can be carried in a pocket.

In carrying out the objects of the invention generally stated above it will be understood, of course, that the essential features thereof are necessarily susceptible of changes in details and structuralarrange ments, one preferred and practical embodiment-of which is shown in the accompany ing drawings, wherein Figure 1 is a perspective view of the improved cup as it apcpears when ready-to be used. Fig. 2 is as e view of the cup when folded. Fig. 3 is a planof the blank from which the body of the cup is formed.

, Referring to the accompanying drawings by numerals, it will be seen that the improved cup comprises "a body 1 that is formed from a single sheet of metal or other resilient sheet material, said sheet being elongated and provided with a central transverse fold line 2. The ends of the sheet are provided with central longitudinal slits 3 which extend toward the fold line 2 and from the ends of said slits, diverging slits 4 extend adjacent to theends of the said fold line 2. This arrangement of slits and fold line provides the four sides 5 of the body and the inclined bottom surfaces 6.

A supporting and edge-sealingframe is provided for the body, said framebeing formed of thin flexible sheet metal or other suitable material shaped toprovide the strips 7 that overlap and seal the junction of the meeting edges of the sides 5, the shortstrips 8 that overlap and seal the'slits 3,

and the divergent strips 9 which extend from the strips and therein to the EtQCQHb' v formed extendin Fatented May *7, 1912.

divergent slits 4. Said frame is rigidly fas toned to the body over the meeting edges thereof, and, being flexible, serve as hinges to allow said body to be opened, as indicated in Fig. l, or folded as indicated in Fig. 2

the improved cup can be readily folded and placed in an envelop or the like and sealed, so thatthe same can be kept in a perfectly sanitary condition; also that the same being of sheet material, the blank thereof can be quickly and economically produced and then readily set-up in operative condition.

What we claim as our invention is':-

In, a device of the kind formed from a blank comprising a central diamond-shaped from one obtuse angle to the other, said blank further having extensions from the sides of the diamond-shaped portion defined therefrom by fold lines form ing the outline-of the diamond shaped central portion, each of said extensions having a curved outer edge and being united in pairs along fold lines forming the prolongation of the diagonal line of the diamond extending from one acute angle tothe other and having the other edges free inclined toward each other; in combination with a frame formed from a single piece of thin flexible material, said frame comprising a overlap the seal the.

central diamond shaped portion overlapping the,fold lines between the central portion of the blank and the extensions,said central portion of the frame having extensions from its acute angles overlapping the fold lines between the adjacent extensions of the blank, said frame further Gr.

It will be seen from the foregoing that,
